disappearing cosmetic threads

Am I the only this happens to? I have a drawing with sectionviews. The sections cut through the axis of several threaded holes.The cosmetic threads appear correctly. Close the drawing. Work onsomething else. Re-open the drawing and the cosmetic threads havedisappeared. Go to the part, edit the tapped hole feature to showthe threads as a diameter. Save the drawing. Re-edit the tappedhole feature to show the threads as cosmetic threads. Save. Re-openthe drawing. SOMETIMES this fixes the problem, but onlytemporarily. I am running 2008 s.p.1.1, but this was also a problemwith 2007. The video card is a Quadro FX1300, with the latestapproved drivers downloaded from Solidworks.
